Do you want to play with the slinky, but got no stairs? Jim Sellers has got you covered! Behold The Slink-O-Matic, a device that will do the slinking for you:

It "slinks" a slinky for you at times when there are no stairs and you just have to... Also useful in determining whether one is in the northern or the southern hemisphere. Due to Coriolis forces it will "slink" from right to left in the northern hemisphere and from left to right in the southern hemisphere. ;-)
